Hi! You're saying that this is a Romanowsky type stain? Well, the nuclear detail seems to show this is in fact a PAP stain!!! ??? :P

These cells seem a bit deteriorated and there is cellular dissociation and what appears to be diathesis?. The scant, basophilic and fragile cytoplasm seems to show these are glandular-type cells. The big, pleomorphic nuclei (one with conspicuous nucleolus) also points towards adenocarcinoma. Thought the photo is not the greatest, nor I can compare the cells with the rest of the slide, I would say Invasive Adenocarcinoma (at least).
